I agree with your approach but would try to avoid using the $card->country call twice.

my $country = $card->country;
$country =
   $country
   ? $country eq q{gbr}
     ? q{}
     : qq{[\U$country]}
   : q{};

I am unsure of the best way to lay out nested ternaries but have found the above indented multi-line approach, with associated condition, true and false all aligned, quite readable. Others may disagree.

Cheers,
