It took me a while to adjust to the sound of my LS50s, and a lot of that had to do with getting the toe in correct. Unlike you, I was coming from speakers with a more rolled off treble, and the KEFs seemed overly bright, but there was a similar adjustment period. They sound perfect to me now. I think our ears adjust more than the gear changes during break in.
Speaking of which, the way you describe the sound of your R3 Metas sounds pretty close to ideal. I’ve demo’d the R3s recently and definitely didn’t find them lacking in treble detail. And your amps should be an amazing match as KEFs seem to really like powerful class D - their active speakers all use high watt class D amps, except for A/B in the tweeters of the LS50 Wireless and LS60.
It's worth noting that, unlike the R3, the original LS50 has the tweeter response shelved up by some 2.5dB:
