Gained only 4 more seats to make a massive 12 and received a lower share of the vote than their 2015 wipe out where they lost 49 seats.

That's a 50% swing. Given how little goodwill they had after the coalition that's significant.
You're also not actually claiming that a general election was a second referendum because that's a little bit silly.
