looking at these two entities, it appears that only genres are currently showing on the release and artist pages. I'd expect to see all tags on these pages, especially since it says "Tags".

• Excited About Burger (2021) — ListenBrainz (no genre tags, so no tags show up)
• Vylet Pony — ListenBrainz (only genre tags appear, note the lack of Brony and indie tags)

whether these are split into two sections or maybe different colors, I don't mind however it's implemented.
