The America’s (as in 2 continents) have a combined market share of 29% so the US share will probably be below 20%.
If the other 80+% are willing to spend money on these systems the US share is basically irrelevant for “advancement in technology”.
Emerging markets like China and India will become far more important if they keep on growing.
The US population is about 317 million (little over 4% of the world population)
China: 1,360 million (19%)
India: 1,241 million (17%)
What are the respective GDPs and per capita incomes of those countries? What does that mean in terms of purchasing power for 'luxury goods'? Population growth isn't everything. Using some of your numbers, 5% of the population is buying 29% of the world's cameras. Also, I would guess the US accounts for ~25% of the market - by stating the US population of 4.44% as a 'little over 4%', your rounding error is almost the population of Canada.
