I do think for movies and multichannel recording music, the center channel is important. Also, the so called timbre matching is sort of a myth, not entirely but just sort of... The fact is, if two speakers measured the same or similar enough, they will have the same timbre. People tend to to think it matters whether how the speakers are made, but in reality, while if made differently the likelihood of them sounding the same will naturally be less, so it is better that they are made the same, all else being equal. However, all else being equal is hardly the case, so in the end, it is the basic metrics such as frequency response, transient response, distortions (all kinds), voltage/current handling capabilities etc., that really make the difference. So, if your new speakers measure more similar to your front speakers than than the old one did, then it should be a better match sonically speakers, regardless of how and who made the speakers.
Sorry, I was trained as an engineer and I guess I ended up thinking like one too lol..., so to me, just look at the objective, verifiable facts. In audio science, there is nothing
matters to what we hear than cannot be measured, if there are, and of course there are, then it still won't matter because it would mean whether the products would sound "different, better", or whatever.., would be by chance not by design anyway so in that case, unless one can to do in home comparison of numerous products, one would not be able to pick what's best...
The bottom line is, you succeeded in choosing your center speaker based on objective facts, not myth (again, just sort of), so, congratulations! I probably will replace my center speaker with a Revel or KEF one too, hopefully sooner than later.
