your trueview photo is overexposed so not that good to help out here and your in hand photos the lighting is not very good to see the toning properly. it can be a challenge to photograph proofs especially in a holder. lay the coin on a flat surface. do not use any overhead light or flash. based on what I can see your coin would not be considered Amazing, I would place it in the Above Average toning box. it would not have added any bump in the grade imo.
here is some insight into how PCGS looks at toning for both MS and Proof coins
PCGS uses seven levels for toning: Amazing, Positive, Above Average, Neutral, Below Average, Negative, Ugly.
MS/PR68 - Must have positive eye appeal.
MS/PR67 - Must have above average eye appeal.
MS/PR66 - Cannot have below average eye appeal.
MS/PR65 - Cannot have negative eye appeal; can have below average luster/toning only if outstanding in all other areas
For silver coins, PCGS looks for:
Even, subtle toning (no splotchy or deep embedded color).
Strong, even luster (MS) or deep, clear reflectivity (PR).
Sharp strike (especially for proofs).
Minimal, acceptable marks that don't hurt the visual impact.
Meeting minimum eye appeal levels for the grade.
If a coin meets the technical grade but has poor eye appeal, it may be downgraded; conversely, exceptional eye appeal can boost a coin's grade
