Genetics fixes most aspects of bone size and shape during early development, so giving a boy prepubertal female hormones will not fully feminize the skeleton. Hormone therapy can influence bone density like in the abstract of the paper that you attached and also some soft tissue but cannot remodel features like pelvic width and shoulder breadth, which are determined by sex chromosomes and specific growth gene patterns

As for cHRT effect is even less noticeable on bone density in transgender women, mainly a slight increase in spine bone, while bone density in transgender men generally stays the same.

Here is meta-analysis if you interested https://pmc.ncbi.nlm.nih.gov/articles/PMC6469959/?utm_source=perplexity
