The math is right Max. let me explain:
The original question was that a 65000 color palette would show bands in full gradient screen from dark blue at the top to light blue at the bottom and that a 16 million color palette would not.
On the Xperia that would be 800 LINES of 800 different blues.
On the Iphone that would be 480 LINES of 480 different blues.
Assuming that the first dark blue and last light blue are the same on both phones, that means that the Xperia will have in between 320 shades of blue MORE than the iPhone. This Difference is NOTICEABLE it is almost HALF! the number of shades.
But you are right if we talk about pictures. Every picture will be differente in tonality and number of colors. But which one will look better is another topic beyond this post: DETAIL vs COLOR. but quickly think about this:
A very complex detailed and colorful object in one square inch of screen.
the XPERIA will be very detailed object with 96000 pixels with a max of 65000 colors.
The iPhone will be a more blurred object with 26000 pixels and just 26000 colors (!?)
So the answer is: depending of the type of picture.
But what is really wrong is your statement:
... "If you want to show more colours than 65000 colours then you
need a display that has higher resolution"...
I'm not blaming you on this one because I'm sure you didn't mean to say that.
Obviously HIGHER RESOLUTION doesn't make more colors. If your palette is 65000 you can not have more than 65000 doesn't matter what resolution.

Ahem... That's totally wrong.
I going to let you tell me how many shades of gray.
No binary math here, just comon sense:
QUESTION:
In your opinion how many shades of gray are in a palette of more than 16 million colors?? (exactly 1677216 colors)
BTW let me mention this. a full color palette with shades next to each other can ONLY be described on a tri-dimentional space. (topic for another time)

Now, let me think..... Suppose you want to look at a black and white picture.
How many shades of grey with a 16 bits screen?
Ahem.... 32!
With a 24 bits screen?..... 256.
Which screen will show the most banding? On which screen will the same B/W picture show best?
Not completely true.
Read the first paragraph.
Math aside, I seriously doubt if anyone could tell the difference between a 24bit/18bit/16bit image.

@Pinguino2
Thank you for detailed explanation. For me it is enough to know that in practice the difference is not noticable. Otherwise it would bother me

It may be strange, but there are people who can hear the difference between 192k and 128k mp3s and there are who can see the difference between 16 and 24 bit
Most of the people don't, but there are many who can.

I suspect the Vodafone devices may have a different ROM given all the rumours about Vodafone network issues delaying the launch - has anyone already got a Voda X1 -please check the ROM version/date.
On my VODAFONE device I have the following:
ROM Version 1.02.161.7
Rom Date 09/17/08
Radio vaersion 1.06.25.29
Protocol version 52.43.25.24u
ExtPkg version ****
I didn't see 'Extpkg' version listed in Masseur's screen shot so I left the numbers blank incase this was a security issue ( I am new to WM!). But as this a VF FW would ExtPkg just mean extention package? Anyway there is the ROM info for those that are interested.
On my VF device none of the actual VF stuff works. I can get on to other web sites fine but not vodafonelive, vodafone find and go etc. Not yet tried customer services as I am still finding my way around.
The Google panel has been replaced by a VF panel...you can still access google from here aswell as the VF services (that are not working for me). Also found that the 'Design' Panel is missing from the VF version.
Still playing...

@ WhyBe,
Thanks, something new to me.
So when working with grays it doesn't matter if it is 16 bits or 24 bits.
If Photoshop let me pick from a palette of thousands of grays only 256 will be displayed and stored.
Thanks, you always come to the rescue.

No problem...smaller but heavier

Obviously HIGHER RESOLUTION doesn't make more colors. If your palette is 65000 you can not have more than 65000 doesn't matter what resolution.
*************************
You quoted me out of context. I was talking about a hyperphetical display of only 65000 pixels, to illustrate a point. I didn't say that a higher display automatically gives more colours. But if you have a display that can only display a total of 153600 pixels (ie 480x320), then you need a higher display resolution to show more than 153600 colours (that's assuming each pixel is a different colour).
For example if an image has 160000 different colours, then you wouldn't be able to fit all the colours on a 153600 pixel display. (you can have no more than 1 colour per pixel)
So even if iphone can display 16million colours, it can only display AT MAXIMUM 153600 different colours at one time. However this is more than the X1 which can only display 65000 (approx) colours regardless of the resolution. imho this does make a little difference, though as has been pointed out not everyone can tell the difference.
I can (I just produced two images in different colour depths from the same original), however if you didn't have the two side by side I wouldn't notice.
So I'm not arguing that iphone images will look better, the difference is very small. But your maths isn't 100% correct. Unless of course you want to produce a colour chart with 800 neatly lined up shades of blue
Then you would be right.
