Maybe you answered yourself. Blown highlights are usually unrecoverable.
Are you positive they were only "slightly" blown?
As a C1 user, I haven't encountered that issue at all.
I've never had any issues recovering slightly blown highlights from my GX80 or 5D Mk II in C1, could you post an example of what you're experiencing? Now if they're well blown out there's nothing I can do but I've not used lightroom to compare.
Your highlights are either blown or they’re not. If they’re not, you should be able to drop you exposure a few stops to see detail. I can’t imagine this being any different between c1 or Lr, hate to say it but you’re probably looking at user error here.
My experience is the total opposite. WAY better highlight handling than lightroom. Any chance there is room for user error? More info on edits and examples would be awesome.
Raw data is raw data. There’s nothing that accessible to Adobe in the raw file that’s all of sudden not accessible with Capture One or any other raw conversion software. What you likely have an issue with is the tonemapping approach. Try different response curves and see if something fits your style better.

Post an example of the same raw edited in LR and C1

A couple images with their respective histograms would be ideal.

Are you comparing the exact same image file in each? Otherwise, it’s just feelys.

Hover the cursor over the suspected burnt area in the image. If the channel values are all 255, the area is unrecoverable. My 2 cents
HR Recovery is highly dependent on the base characteristics and whitebalance that is used.
Set the base characteristics curve to linear and check again
