This is probably a stronger reference: https://juniperpublishers.com/jdvs/JDVS.MS.ID.555822.php
Overall, though, the nutritional content is "mostly" unaffected by UHT. B1 and B12 drop roughly 10-20% for both types of pasteurization.
The primary issues with UHT are Lysine and folate. Lysine gets clobbered by the Maillard reactions. The folate you cited is definitely a concern given that folate and Vitamin D are factors in preventing birth defects.
And, you are correct that the taste does change since UHT kicks off Maillard reactions in UHT milk. TIL.
However, we come back to the fact that "standard" HTST pasteurization changes are so minimal that the risks of raw milk FAR outweigh any possible gains therefrom.
And if you don't have a reliable cold chain, UHT pasteurization is pretty good with caveats.
You're also right that apart from the folate the losses are not so dramatic.
Taste is significant though. My kids (spoiled brats) refuse to drink UHT and they recognize it immediately
I hate UHT - and one thing I've learnt from cheap hotels is a teaspoon of natural yoghurt makes the milk taste fresh enough to me to have with cereal. Not sure why.
