I've flown Latam version of A350 twice now. They are not Latam planes...they are former Latam planes purchased by Delta 4 years ago and placed into service while Delta awaits delivery of new planes. I've only flown Delta One on these planes so I will limit my comments to the same. Where a few people complain that they dislike these planes, I'm a fan given how large the leg room is vs. other Delta One products on planes like the 767s, A330s and A340s. Though they are not as nice as the standard Delta A350s, they are superior to many other products and I won't complain very loudly. You also benefit from using Global Upgrades directly from Comfort vs. Premium Select. Enjoy.
