This paper notes a study that disagrees:
"A study looking at the stability of Blu-ray media has shown that 
 overall, BD-Rs (whether they are the dye or the non-dye type) have 
 rather poor stability compared to some CD-Rs and DVD+/-Rs (Iraci 
 2018)."

Unfortunately "Iraci 2018" is behind a paywall.

They do give "BD-R (non-dye, gold metal layer)" 10-20 years in a
good storage environment, and curiously "BD-RE (erasable Blu-ray)"
gets 20 to 50 years.
