The results are out... Looking pretty off for now...
Here is PCA with both my original g25 coordinates and imputed coordinates (both from illustrativeDNA)

The imputed one seems to detect your ancient Bulgarian ancestry (Southeast asian traces), I would say it's pretty accurate and it was worth trying. That's why you shift towards Balkan turks, not because you're a turk, but because of that east asian trace percentage, which Balkan turks also score, for other obvious reasons.

It's not 100% accurate but it's likely.
https://www.ancestry.com/c/dna-learn...n-and-geneticsWhile reliable, imputation has a higher rate of error than simply reading the DNA. Here are several reasons how imputation accuracy can be affected:
The surrounding markers may be too similar to easily tell apart. This can make it difficult to distinguish the different haplotypes and impute any missing data they contain.
Haplotypes and their frequencies can vary between populations. This variation can sometimes lead to biases in imputation results.
If the marker that can’t be read is near the end of a chromosome, then there may not be enough markers on either side of it to act as indicators.
These are just a few of the ways imputation can sometimes be less reliable than directly reading the DNA.

Distances to modern samples became bad after imputation, though.
If you are interested, you can check my parents' results on IllustrativeDNA here, if it has any significance for the imputed results...
