What happened to the theme packs?

[Edited after seeing Erin1995j 's posts that were entered while I was writing this.]

Roku used to have a number of different theme packs that included wallpaper, screen saver, and sound effects, all bundled together and keyed to a particular theme.  Former Theme Pack names I recall are Daydream, Decaf, Graphene, and Nebula.  This is in addition to any temporary occasional sponsored or seasonal item.

I've checked on my highest and lowest Roku models, and the only Theme Pack I'm shown now is the purple default Roku Theme Pack.  I'll be interested to see if I get any others back like Erin1995j did.  [Edited even later -- Sorry I was looking at the "My theme packs" line where only the default shows.  Below that, in the "Popular theme packs" section I currently have the following 6 theme packs available on all my Rokus: Space, Nautical, Jungle, Western, Romance, and Kids.]

There are still a wide variety of wallpapers and screen savers, both from Roku and others, and several sound effect groupings from Roku, all available, that one can choose to build one's own semi-custom theme.

My favorite Theme Pack was the one called Nebula mentioned above that I had on my two Rokus at the time.  Unfortunately I learned that, if I have an old Theme Pack installed that I like, I shouldn't switch out of it because I can't get it back.  I learned this lesson on one Roku in time to keep me from switching out of it on the second one, where I'm still running it years later.  I have found, at least, that I can still switch between currently available screen savers without losing the Nebula wallpaper on that Roku.  If I ever have to do a Factory Reset on this Roku, I expect I'll lose that too.
