I doubt that the panel is 10-bits, but I can't say for sure. The color gamut of a display is primarily determined by the color spectrum abilities of the backlighting tech used (CCFL, LED, etc). Internet is sRGB for the most part, yes, but browsers are becoming better at being aware of the color profile tagged within an image and displaying it properly (provided the rest of your hardware and OS is capable). Apple has finally brought OS-level color management to iOS (started with iOS 9 if I recall) and this is what allows them to display both P3 images and sRGB properly on the display. They basically brought ColorSync from OSX over to iOS and it's a great move. Android doesn't have this kind of color management yet, but I'm sure they won't be far behind.
OLED doesn't always have to be oversaturated, kinda depends on what the manufacturer wants to set it as. The fact that OLED could produce such vibrant colors was a selling point for phone makers to differentiate themselves. Samsung's latest OLED displays are incredibly accurate if you set them to be and I'm sure if Apple does switch to it for the next iPhone that their display will be as good or better as the current one on the 7.
There's no way Apple would let a future display be crazy over saturated and inaccurate, even if it's OLED. Years of the screen being slightly too blue aside, the 7 has a noticeably warmer (more accurate) tint and I don't think they're going back
