I could definitely be wrong here but it seems that not having the Jh blocker adds only a 8% higher probability of villain having a flush. I arrived at 8% because 3 hearts are out instead of 4, so the remaining flush cards make up 10/13 (77%) vs. 9/13 (69%). Let's say Villain has a flush here even HALF of the time, not having the blocker makes him only 4% more likely to have the flush (.5 x .08 + .5 = .54).
IMO, Villain should not be xR any portion of his range on river unless he is against an opponent who is a combination of someone who 1) overfolds (and he is xR as a bluff) and 2) is very stabby. Sometimes even experts will get bored, have fancy play syndrome, and mix it up for fun here as well. As played, I think you played the hand correctly and wouldn't worry about not having the Jh blocker that much.
As a side note, I generally think experts nowadays are overvaluing blockers in limit. Sure it increases Villain's chances of having a flush by 8% but this isn't NL or PLO where that 8% of an all-in is a large factor - there are a lot more important decisions going on in hands than blockers in LHE and I think there are only a few rare instances where it should really be factored into your decision making in HU, non 4-flush board pots. As I've watched some RIO RunLikePanda vids it amazes me how much of his and other "experts" decision making factors into blockers where they are missing out on the larger piece of the puzzle. Last, by no means am I saying these players are playing poorly, just that their brainpower should move toward other factors
