5 years ago I (metamilo#7850) suspect it may have something to do with the default pages since the runes for that participant are identical to the ones for the default page named "Resolve: The Colossus". If this is true then it should show perkSubStyle = 8200.
From the response we get the following values for participant 3. perk0: 8437 perk1: 8446 perk2: 8444 perk3: 8451 perk4: 8224 perk5: 8237
And from the communitydragon perkstyles.json located here https://raw.communitydragon.org/latest/plugins/rcp-be-lol-game-data/global/default/v1/perkstyles.json
"defaultPageName":"Resolve: The Colossus","defaultSubStyle":8200,"defaultPerks":[8437,8446,8444,8451,8224,8237,5008,5002,5001]

In very rare cases (and even then, only on some of the participants), the perkSubStyle field is not present in the response when in a game after runes reforged, all participants should have that field.
Developer impact: I'd say minor inconvenience cause it can be calculated based on the selected runes (which are present) Player impact: None cause the client doesn't display the secondary tree, it only displays the runes picked from it. (but the ACS response doesn't have that field either)
According to metamilo#7850 on the discord, this happens once every 100k games and the only match he could provide for you to look at was 3073596764 on NA. In that game, the 3rd participant was missing the perkSubStyle field.
