When you A/b test the sound in a controlled environment, yes you can perk your ears and hear 'something'. Questions: How many people make music in a controlled environment with another guitar next to you so that you can hear the minute difference that it makes? If heard blindfolded, could you tell which wood was which? Is paying an extra $1000 for that 'AAAA' maple cap worth the difference in the sound that only you can hear (barring that you don't drag around another player with you always so that you can A/B test to prove your wood choice)? In a live setting, or recording..... do you really hear those differences? Can you honestly pick out whether a LPC or LP STD is being played on a recording? Now test your conclusions.
