Angle? Bad ruling? Both?

$180 PLO Tournament at Champions Houston. Players can rebuy for $100 and can add-on 50K chips for $100 at the first break.

Villain in early position (I think small blind), hero in middle position to my right.

Villain is a tournament regular in the Houston area and is a very aggressive player.

Blinds are 200/400 with a BB ante of 200. Champions plays "true pot" preflop which makes an open 4x the big blind.

Villain opens to around 2500, there were some limpers.

Pot grows significantly.

Flop is 9♦ 9x K♦

By the turn, which is A♦ , villain announces "pot",and slides out about 8 or 9 pink chips (5K denom). Hero quickly announces all in for about 35K.

Villain announces "Full house is good", and tables nut flush with Q♦ 4♦ Kx Tx, but doesn't put out anymore chips, because the 8 or 9 pinks covers hero.

Hero acknowledges full house and shows 9x Kx x x
Dealer rips river, which won't change outcome, because villain can't make a better hand.

Villain then says, "I never said call", and wants the floor to come make a ruling.

Floor is then called over and dealer explains what happened. Floor says something like, "The action going to stand, and you're going to pay off his bet"(which was around 6K more than villain's pot-sized bet on the turn).

Villain starts arguing that it's not about the chips, but the "bad ruling". Hero is like "come on, this really looks like an angle." All-in bet is paid off and we move to the next hand where Villain is still arguing with floor.

Thoughts?

Does exposing his hand before announcing "call" kill his hand?
