How can I check data deduplication ratio/savings?

TS-855eU-RP, QuTS hero h5.2.2.2952.
I have deduplication enabled on one share that is used for backup. I want to know out how much space is saved thanks to deduplication, but I can’t find any information about it anywhere. There is only information about compression savings.

Under Storage Pool Management “Data Reduction” you can see the ‘success’ of it

Thanks, this is it. Looks like it’s useless for us.
