I don't think every episode is animated with this much fidelity. Maybe reserved for the pilot and a few others throughout the season. I watched Goof Troop a few years back and some animations looked like movie quality while others looked like they were animated with a potato.

Never thought I’d see a Goof Troop reference in the year 2024, on the internet! 😳

For sure there were different studios and different teams of varying quality levels, and they'd assign out episodes or sequences ranked by how important those scenes were to look their best. I do miss the days of (relatively) full animation rather than manipulated symbols, tho. 😞

Been rewatching Gargoyles lately and it's very much this. Most of it IS well animated, but you can tell the higher quality stuff is mostly towards the starts of the seasons and big story moments.
