According from Emulator Color Depth on Windows Phone 7 forum, I just heard about limitation of Silverlight on Windows Phone 7 that it display only 16-bit color-depth image on Silverlight application just like previous version of Windows Mobile.
Is it true? Anyone can confirm this.
PS.Normally, Silverlight natively support 32-bit color-depth and all modern smart phones also support 24-bit color-depth. I'm not sure what color-depth will be displayed. I have quite bad experience for using HTC Sense in windows mobile 6.5 on my Omnia Pro 2(OLED display with 24-bit color-depth support).
Thanks,
