Input Attributes That Are Uppercased Get Snaked

return str_replace('_', ' ', Str::snake($attribute));

If i have an input that is all uppercase i may not want it to get snaked.
For instance i have a csv file with uppercased headings. I'm transforming the csv into a string indexed array and then running validator rules on each entry in the array.
But when errors are found and the message is created my message looks something like this:

The d a t e b r o a d c a s t format is invalid

The input attribute is 'DATE BROADCAST'.
Would it be better to check if the attribute is all uppercased and only if it isn't to snake case it?
Btw i am aware that i can specify a language line for the attribute but i feel that i shouldn't have to do this. Be interested to know everyone's thoughts.
