One way to know for sure, and i'm sorry but it's a total pain in the arse, is to swap the discs over then take off the right caliper, put a block or whatever between the pads to stop the pistons coming out and tape it up to make it secure, then cable tie the caliper out of the way.
So all you are left with is the original right disc working with the left caliper ONLY.
As i said a total pain in the bum but if it doesn't judder then you know you have a good disc and the problem is elsewhere.
It's time consuming, but definitely money saving if it turns out to be okay.
I have been through all of this several times which ultimately ended up with me replacing the front end of the bike, until the last thing to look at was the braided lines, and if i didn't know better now i would've still not thought they were the culprit as they weren't leaking or anything!
If you do choose to do what i suggested, be prepared for siezed disc bolts, and on removal make sure it is absolutely spotless on the hub under the disc before reassembly.
And don't even think about skimming the disc either, they're not thick enough at all to do that.
