M5Stack Tab5's backlight doesn't need PWM inversion - the official demo uses direct duty cycle without any inversion flag. (#1764)

Browse Source 
uint32_t duty_cycle = (4095 * brightness_percent) / 100;
ledc_set_duty(LEDC_LOW_SPEED_MODE, LCD_LEDC_CH, duty_cycle);

Tested on M5Stack Tab5, the screen brightness is working correctly now, previously it's reversed.
