Even Sonic Mania? And SoR4?
Sonic Mania is a Sega game, it's produced, published and co-developed by Sega (even if it's just few staff from sonic team).
While SOR4 no, Sega only had a little supervising role, the publisher was DotEmu, Sega just got royalties from the Streets of Rage license, similar to Bayonetta 3 to make another example.
