> FunnyPlaying IPS V2 display How are the colors on this replacement display? With GBA the colors are kinda complicated topic because AGS-101 colors are very different from the original AGS-001, to the point where games can end up looking over-saturated and cartoonish.

Yeah, their website is way too light on details. A common problem with GBA replacement screens is the resolution of 160 by 144 leads to rectangular pixels, which is a big no no. I dug around and found a reference to a problem with the screen's buffer causing visual tearing. That screen is a no-go for me. The Analogue Pocket is still the display king.

  The AGB's resolution is 240x160. The panel used is new-old-stock or reproduction equivalent from the BlackBerry Curve 9380: a 480x360 panel, which allows the AGB adapter to output a 2x integer-scaled 480x240 image. When playing a DMG or CGB game, the image is still 2x but otherwise the image and behavior comes from the stock AGB hardware: a default scale places a 160x144 image in the center of the display, and pressing the L and R buttons allow you to toggle between that native mode and a horizontally stretched mode (that basically nobody likes). The tearing existed in the initial version of the adapter ribbon, as the 9380's display driver refreshes the display in portrait rather than the AGB's landscape. The second revision of the adapter, which started shipping only a couple months after the initial, way back in 2019, adds a 1-frame buffer to output the signal in the way that the display driver expects. The AGB's frame rate is a hair under 60Hz, so this does introduce a 16ms delay, but in the vast majority of AGB games this drawback is outweighed by all of the other benefits.

They're more accurate to what we would recognize as the RGB value on a modern device, as opposed to accurate to the classic AGB display—or "over-saturated and cartoonish." Some people like this, others don't. I sense you might know this, but for others' reference, some later AGB games have settings to optimize colors for AGB/AGS-001 or AGS-101 displays. That's sort of the best we have unless new adapters are released that allow for additional configuration, like some of the recent Game Boy Color kits utilizing the BlackBerry Q5 displays. There's another kit released by FunnyPlaying recently that utilizes new old stock of the lower display of the DSi. They perform similarly to the 101 displays, which to your point are still more saturated and RGB-accurate but still not as much as the BlackBerry 9380 displays used in the IPS v2 kit.
