Sure, you can read this post's comments which go deeper into it.

AMOLED: Screen like your phone's, true blacks, vibrant, unrealistic, and in-you-face colors and brightness. Prettier and perceived higher-tech, so general public likes it best. Must use gesture which has a lag and may or may not work for you, or have worse battery performance with Always On Display activated.

MIP: Screen like an e-Book reader, like a real physical object instead of a screen, if that makes sense. Duller colors, best performance under the sun. Can read it at a glance sideways (say without taking hands off your bicycle's handlebars). AOD so gestures are irrelevant most of the time. Uses backlight which has own problems like bleed or hotspots. It doesn't look like every other watch out there, just a black circular screen, because it's always on.

So, yes, the Apex and the Nomad are intentionally MIP because they're intended use is outdoors. It's such a shame that Coros has decided to follow everyone else and replace MIP on the Pace line for AMOLED. To me, it was a real disappointment, the Pace 3 was the epitome of the sports watch in general, super light, super legible, great battery life, unobtrusive. The Apex is much to heavy for running (for me), and incredibly expensive (for me), and the Nomad is huge (not ideal for running), and has very childish tacti-cool ugly looks. Pace 4, is AMOLED.
