How to check if my i1 Display Pro needs to be replaced?

EDIT: After viewing some quick calibration results, I'm just going to replace this 5 year old meter.

I've had this for 5 years and I've heard the filters become inaccurate after awhile. I haven't used it in 3 years or so. When calibrating 2pt on an LG E6, I had to adjust green -35 and red + 34 at 20%, while 80% needed only minor adjustments. This doesn't feel right. I am also seeing some significant skewing on the CIE chart. Based on reviews, it shouldn't be this far off with ISF expert defaults profile, so it could be a user error with HCFR settings or it could be that my meter is just old.

Compare its readings with those from a known good meter on the same TV. That's really the only way to tell.

Hi, you are measuring the Wide Gamut, so the colors are very saturated compared to the REC.709 colorspace.

Ideally you need a spectro, to create a meter correction table for your colorimeter, so to fix any inaccuracy, as its unknown if has large or small the problem now.
